Which is a fantasy world, because unless that person is insane and can't find anyone else, you WONT find someone stable that is going to put up with your shit if you can't bring anything at all to the table.
Going to power level a bit here and say I have dated emotionally unstable women before, and when I say emotionally unstable I actually mean pretending they are about to kill themselves for hours for your undivided attention, and then a few minutes later go "I was just testing to see how much you care about me!"
So no, you never want to stick your dick in crazy. Clingy people are also annoying, I can not fathom why anyone would want someone to constantly stalk them, breathe down their neck, and isolate them from doing things.
